CAR-WHEEL MOUNTING.

Specification of Letters Patent.

Application filed September 9, 1918. Serial No. 253,331.

To all LU/1.0m t may concern:

Be it known that I, LEROY G. BINKLEY, a citizen of the United States, residing at hicago, in the county of Cook and State oi' Illinois, have invented certain new and useful Improvements in Car-Vheel Mountings, of which the following' is a specification.

rI`his invention relates to the general art of railway cars, and has reference more parcars. Owing to the sharp curves of the tracks on which mine c'ars travel, it is necessary to mount the wheels of mine cars rotatably upon their axles, and further to provide means for preventing endwise displacement of the wheels from the axles. In one type of mine cars the wheel is attached to the bearing-box of the axle, while in another the wheel is attached to the axle itself. My present invention relates to cars of the latter type, and the main object of the invention is to provide a simple and improved means for locking the wheel on the axle, which shall allow the ready removal ci' the wheel when necessary, and which may also facilitate the oiling of the wheel bearing. Another object is to provide an improved construction wherein the inward thrust of the wheel or the outward thrust of the axle shall be resisted at the outer end ot the axle with a minimum of friction and wear.

Other objects and advantages ot the invention will be apparent to those skilled in the art from the following detailed de-I scription, taken in connection with the accompanying drawing` in which I have illustrated practical and workable embodiments of the invention, and wherein* Figure 1 is vertical section through one ot' the bearingdaoxes and adjacent wheel oi'l a mine carin the plane of the axis oit the axle, showin one embodiment of the invention;

Fig. 2 is a similar view of another embodiment of the same principle, showing a diiierent means for securing' the loclrinqa bolt to the transverse outer end wall ot' the wheel hub. which has the additional function of facilitating the application of lubricant to the wheel bearinrrs and to the washers which receive the end thrust;

Fig. 3 is an enlarged section on the line 3*?) of Fig. 2; and

Fig. i isa view similar to Fig. 3, show- .ing a slight modiiication.

eferring to the drawing, 5 designates the floor of the car body, to the underside of which is secured the axle bearing-box 6, this latter being formed with a bearing opening or-passage 7 to receive the axle 8 and at its outer end with an annular flange Patented Feb. 3, 1920.

9. The axle 8 projectsl beyond the 4outer end of the bearing-box, and on the projecting end is mounted, preferably by rollerbearings 10 and a hardened steel bushing 11, the hub 12 of a wheel 18.

The outer end of the axle 8 is formed with a recess 14 the wall of which is preferably tapped for a distance inwardly of its outer end as shown, and in this recess is housed the head 15 of a locking bolt, the bolt-head being eoniined in member in the form ot' circles the shank or stem of the bolt and is screwed into the tapped end of the recess. The bolt has a reduced portion of its shank squared, as shown at 17, this squared portion. iitting a square recess or hole formed in the outer` end wall 12 of the hub 12; and the outer end of the bolt, beyond the squared portion, is threaded to receive a nut 18 preferably countersunk in the outer side oi the end wall of the hub. By this means the wheel hub is securely locked to the axle, while tree to rotate on the latter; and by simply removing the nut 18 the wheel may be withdrawn from the axle.

Encircling the shank of the locking bolt and lying between the outer end of the axle 8 and the end wall of the hub are a plurality of metal washers 19 which receive the wear caused by relative end thrusts between said parts.

The inner end 12 a nut 16 that enhub is formed with a longitudinal recess 20,.

the recess 14 of the a transverse recess 21 the longitudinal recess 20. of the locking bolt, which in be round throughout, lies in opposite and in line with axle, and also with that intersects The shank 17 this case may this recess by a retaining l the recess 2O and is formed near its outer end with an annular groove 22 that is engaged by a locking-pin 23 set in the transverse recess 21. The pin 23 is retained in place by a plug 24 screwed into and .closing the open end of the recess 2l. @ne very considere ble advantage of this construction is that the recesses 21 and 2O may be utilized as oil ducts for lubricating the end-thrust washers and the bearings of the wheel by simply removing the plug 24C and introducing the nozzle of an oil can or a grease gun to the open end of the recess 21.

In the modication. shown in Fig. 4, the shank 17 of the locking bolt omits the annular groove 22 of Figs. 2 and 3, and in lieu thereof is provided with a transverse hole 25, through which is passed the locking-pin 23. Otherwise, this construction is the same as that of Figs. 2 and 3.

It is believed that the foregoing description, in connection with the drawings, will make clear to those familiar with this art how the stated objects and advantages of the invention are obtained in the structures illustrated and described. Manifestly other changes in the detail structure and arrangement of the parts may be made without altering the substantial character of the invention or sacrificing any of the advantages thereof; and hence l reserve all such variations and modifications as fall within the spirit and purview of the appended claims.

I claim:

vl. In a carl wheel mounting, the combination of an axle having a recess in its outer end, a wheel hub mounted on said axle and formed with an outer end wall having a longitudinal recess opposite and in line with the recess of said axle and a transverse ,recess intersecting said longitudinal recess, a bolt having its shank disposed in said l0ngitudi nal recess and its head disposed in the recess of said axle, means for confining ysaid bolt-head in said axle recess, and a locking pin for said bolt disposed in said transverse recess.

2. ln a car wheel mounting, the combination of an axle having a recess in its outer end, a wheel hub mounted on said axle and formed with an outer end wall having a longitudinal recess opposite and in line with the recess of said axle and a transverse recess intersecting said longitudinal recess, a bolt having its shank disposed in said longitudinal recess and its head disposed in the recess of said axle, means for confining said bolt-head in said axle recess, a pin in said transverse recess lockingly engaging said bolt, and means for confining said pin in said transverse recess.
